As I mentioned in
<http://www.w3.org/mid/p0624062ac2f3582dbb44@%5B192.168.0.101%5D>, Safari
(2.0.4) doesn't present the image, but instead the contents of <object>, when
@type is set to image/*. (If that's fixed in Safari 3, that's great :))

It does, yes. (Well, at least for the PNG I tested with.)

Fallback, yes. But equivalents? The current HTML5 draft speaks very
specifically of fallback only, and seems to mean <video><a href="URL">click

Looking forward to that :) Is it for <audio>/<video> exclusively, or would it
apply to stuff like <img>, <object>, <embed>, <canvas> and <table> as well?

But <embed> is empty; offers no way to provide equivalents. It may be best
today, but should that really be best tomorrow?

True, but we should do it in such a way that equivalents are possible.
